Paul Daugerdas, a former Jenkens & Gilchrist lawyer, and two other defendants in what a judge called the biggest U.S. tax-fraud prosecution in history won a new trial after a juror disclosed she hid details of her past, including that she was an alcoholic and a suspended attorney.

U.S. District Judge William Pauley in Manhattan today overturned the convictions, ruling that the presence of Catherine Conrad, who was Juror No. 1, denied the three a fair trial. “While Conrad claimed that she was a ‘fair and unbiased’ juror, this court cannot credit that assertion,” Pauley said in an opinion today. “Conrad is a pathological liar and utterly untrustworthy.”
